PP composite material with negative ion release function, preparation method and application thereof

Abstract

The invention discloses a PP composite material with negative ion release function, a preparation method and application thereof. The PP composite material comprises the following components by weightpercentage: 40-70% of copolymerized PP; 10-40% of self-made negative ion powder; 1-3% of self-made hollow glass beads; 1-3% of a scratch resistant assistant; 1-3% of a weather-proof and aging resistant assistant; 10-15% of a toughening agent; 5-10% of talcum powder; 1-5% of superactive nano-calcium; 0.5-1% of an odor adsorbent; 0.1-0.5% of a lubricant; and 0.2-0.5% of a coupling agent. The PP composite material prepared by the method provided by the invention has the advantages of large negative ion release amount, and excellent bactericidal and bacteriostatic effects, good sound absorption and noise reduction effects, low shrinkage, and excellent mechanical properties.

Description

technical field [0001] The invention relates to the field of automotive interior materials, in particular, the invention relates to a polypropylene composite material and its preparation method and application. Background technique [0002] As a general-purpose plastic, polypropylene itself has many advantages.

Problems solved by technology

In order to improve the air in the car, people try to add negative ion powder to the plastic, such as patent CN106750906, the static surface negative ion concentration can reach up to 780 / cm 3 , but not ideal

Patent CN 106496794 discloses a method for preparing negative ion plastic interior parts with the function of purifying the air in the car. The interior parts prepared by this method have a very high amount of negative ion release, but there are many types of additives used in the preparation process. The preparation process is complicated, and many small molecule additives are easy to migrate to the plastic surface over time, and many small molecule additives are additives with poor environmental performance. For younger children, they like to mess around Licking indiscriminately will affect the health of children
